To all whom it may concern:

Be it known that I, lFRANCIS MCM. HOLLI- lDAY, a citizen of the United States, residing y at Glade Mills, in the county of Butler and cocks now in use.

Another objectof my invention is to .pro-

. vide means for locking the turning plug. se-

curely in the casing. l

The invention consists of the novel features of construction, combination and arrangement of parts, hereinafter fully described and pointed out in the claims.

In the drawings forming a part of this speciiicationz-Figure l is a perspective view of my improved stop cockt Fig. 2 is a vertical sectional view'of the cock. Fig. 3 is a horizontal sectional view of the cock.

In the drawings A, indicates the valve oasiiig which is rovided with the usual oppositely dis' ose 'horizontal screw-threaded inlet port ,and outlet port A2, having a tapering vertical plugA opening A3, formed intermediate the inlet and outlet orts provided with a waste passage A4, leading out to one side. I

yThe top of the casing is rovided with a` bridge B, extending upward y and across the tapering plug,l being'providedwith an o en- Ving B', in which the reduced end C', o the threaded bolt C, is secured by a pin D, .passing throu h anopening C2, in the bolt. The upper en of thebolt C, isformed square as sliowli at 03,*so that it can be easily turned with a wrench. A hollow tapering plug E, provided with a wrench receiving head is adapted to work in the tapering openin'g and is provided with oppositely disposed vertical slots E', forming a horizontal assage adapted to communicate with the niet port and outlet port. Thetop of the plug is provided with a threaded recess E2, in which the threaded end of the.

bolt is' adapted to work and by means of the bolt the plug can be drawn up into the tapering socket,- so' as to form a perfect watertight joint, or forced out of the` opening so as to overcome the difficulty of having to drive vthe plug out with a hammer or wrench.

The casing is provided with oppositely dis posed slots A5, leading into the taperin opening adapted to register with spaced sots E3 crossing each other at right angles, formed in 'fthe plug E, and throughwhich a key F, is

adapted to pass and secure the lug in a closed or opened position as desire Having thus fully described my linvention,

" what l claim as'new and desire to secure by Letters Patent is y 1. In a device of the kind described, the

lcombination 'with a valve casing provided witll a tapering opening intermediate the inlet and outlet ports and havinga waste passage communicating therewith,v alid a' bridge formed integral with the casing on the' topv and provided with an opening, ofa hollow Itapering plug arranged in said tapering open' ing and provided with oppositely disposedl vertical slots forming ahorizontal passage,f

a wrench receiving head formed on one end of said plug and a threaded recess formed on the other end, a threaded bolt secured in said threaded recess provided with a reduced end extending through the opening of the bridge and having a transverse bore extending therethrough in a plane above'the bridge, and a pin arranged in said bore for locking said plug in said casing.
